Lawn Square Footage Calculator
Add and subtract areas to get the mowable grass.
Lawn Calculators from Measuring to Invoicing
Everything on a lawn starts from one number: the square footage of the grass. Measure that once and the rest follows from it, whether you are buying seed, timing a cut or pricing a season.
Grass Seed Calculator
Seeding rates by species, new lawn or overseeding.
Lawn Mowing Cost Calculator
What a visit should cost, from either side of the deal.
Lawn Mowing Time Calculator
How long it takes on each of the four machines.
Lawn Mowing Calculator
A season priced as a contract, with the margin on it.
Acres Per Hour Calculator
Work rate from deck width and ground speed.
Calories Burned Mowing
From lawn size, plus the miles you walked behind it.
They all start from one number
Everything on a lawn begins with the square footage of the grass. Not the lot size, the grass. Seed rates, mowing time, what a visit should cost, even the calories you burn: all of them are rates per thousand square feet or per acre, so all of them inherit whatever error is in that first figure.
So measure it once, properly, and reuse it. Get it wrong and every other number on this page is wrong by the same margin, in the same direction, every time.
